I don't have a name for the style, but usually with these only one of the button rows is functional, covering the opening of the jacket underneath. Now in contemporary fashion it would probably have a zipper underneath the flappy bit, but your reference makes the top underneath look solid. Pic related for what it probably would look like under the flap, except the zipper is now on top. I had some results that vaguely look like the reference when googling "double breasted military jacket" so maybe springboard from that?

Another garment that comes to mind is a Howie lab coat but those have the button flap go to the top.
